Abstract

The invention provides valve devices in sewer blockage-removing and protecting equipment, and belongs to the technical field of machinery. The blockage-removing and protecting equipment comprises a machine frame, each valve device comprises two driving motors fixed to the machine frame, and output shafts of every two driving motors are fixedly connected through a rotating shaft; each rotating shaft is fixedly provided with a roller I, the machine frame is further rotatably connected with a roller II, isolation belts are drawn between the rollers I and the roller II, two notches are formed in each isolation belt, and the two notches are positioned in equal positions of each isolation belt; the machine frame is provided with communication pipes one-to-one corresponding to each valve device,middle cavities for accommodating the isolation belts are formed in the middle parts of the communication pipes, and each middle cavity divides each communication pipe into a left pipe and a right pipe; and each isolation belt is provided with two longitudinal running sections, wherein one longitudinal running section can block the communication between each left pipe and each middle cavity, and the other longitudinal running section can block the communication between each right pipe and each middle cavity. The valve devices have the advantages of effectively preventing scale deposition and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a valve device in sewer blockage clearing and protection equipment. Background technique [0002] Scaling will occur in the laboratory sewer during use, which will reduce the inner diameter of the pipe and affect the normal sewage discharge; if experimental waste such as animal carcasses enters during the experiment, it will be more difficult to dredge. If the above situation occurs, it is usually dealt with manually, with a pipe dredging machine or by replacing the pipe. In daily life, the biggest workload is the dredging of municipal pipes. The use of these pipelines is more complicated, and the harm caused by clogging is also greater. The dredging of this kind of pipeline generally uses a high-pressure cleaning vehicle to clean the pipeline. The larger the diameter of the pipeline, the higher the performance requirements of the vehicle. Generally, the cleaning range of high...
